Definitions

  • the present invention relates to a ceiling mounted system for use in a surgical theater. More particularly, the present invention relates to an apparatus having articulating arms that support a surgical light, a video camera, and video monitors. The present invention also relates to such an apparatus wherein the articulating arms are inter-changeable between apparatus in different locations and configured to display video images selected from a plurality of video devices.
  • Video monitors are used in surgical theaters for viewing images such as, for example, images produced from lapyroscopic and endoscopic cameras. These monitors display images placed in a position so that the surgeon can view them during a surgical procedure.
  • These monitors are typically mounted on top of a rolling cart that contains the lapyroscopic or endoscopic equipment. This cart is large and bulky and takes up valuable space around the operating table. Since the monitor is on top of the cart, the monitor cannot always be placed in a position that is the most optimum for viewing by the surgeon.
  • Flat screen monitors are compatible with mounting on an arm that is attached to the ceiling. This allows the endoscopic cart to be separated from the video monitor. The cart can then be moved away from the table to different areas ofthe suite out ofthe way ofthe surgeon.
  • the scope is plugged into a wall outlet that is hard wired through the wall and down through the support arms to the video monitors.
  • a surgical camera is movable to different vantage points around the patient, and should even be able to shoot laterally and directly downwardly over the center ofthe patient.
